RESUMO

Per- and polyfluoroalkyl substances (PFAS) in the environment pose persistent and complex threats to human and wildlife health. Around the world, PFAS point sources such as military bases expose thousands of populations of wildlife and game species, with potentially far-reaching implications for population and ecosystem health. But few studies shed light on the extent to which PFAS permeate food webs, particularly ecologically and taxonomically diverse communities of primary and secondary consumers. Here we conducted >2000 assays to measure tissue-concentrations of 17 PFAS in 23 species of mammals and migratory birds at Holloman Air Force Base (AFB), New Mexico, USA, where wastewater catchment lakes form biodiverse oases. PFAS concentrations were among the highest reported in animal tissues, and high levels have persisted for at least three decades. Twenty of 23 species sampled at Holloman AFB were heavily contaminated, representing middle trophic levels and wetland to desert microhabitats, implicating pathways for PFAS uptake: ingestion of surface water, sediments, and soil; foraging on aquatic invertebrates and plants; and preying upon birds or mammals. The hazardous long carbon-chain form, perfluorooctanosulfonic acid (PFOS), was most abundant, with liver concentrations averaging >10,000 ng/g wet weight (ww) in birds and mammals, respectively, and reaching as high 97,000 ng/g ww in a 1994 specimen. Perfluorohexanesulfonic acid (PFHxS) averaged thousands of ng/g ww in the livers of aquatic birds and littoral-zone house mice, but one order of magnitude lower in the livers of upland desert rodent species. Piscivores and upland desert songbirds were relatively uncontaminated. At control sites, PFAS levels were strikingly lower on average and different in composition. In sum, legacy PFAS at this desert oasis have permeated local aquatic and terrestrial food webs across decades, severely contaminating populations of resident and migrant animals, and exposing people via game meat consumption and outdoor recreation.

RESUMO

Humans have profoundly impacted the distribution of plant and animal species over thousands of years. The most direct example of these effects is human-mediated movement of individuals, either through translocation of individuals within their range or through the introduction of species to new habitats. While human involvement may be suspected in species with obvious range disjunctions, it can be difficult to detect natural versus human-mediated dispersal events for populations at the edge of a species' range, and this uncertainty muddles how we understand the evolutionary history of populations and broad biogeographical patterns. Studies combining genetic data with archaeological, linguistic and historical evidence have confirmed prehistoric examples of human-mediated dispersal; however, it is unclear whether these methods can disentangle recent dispersal events, such as species translocated by European colonizers during the past 500 years. We use genomic DNA from historical museum specimens and historical records to evaluate three hypotheses regarding the timing and origin of Northern Bobwhites (Colinus virginianus) in Cuba, whose status as an endemic or introduced population has long been debated. We discovered that bobwhites from southern Mexico arrived in Cuba between the 12th and 16th centuries, followed by the subsequent introduction of bobwhites from the southeastern USA to Cuba between the 18th and 20th centuries. These dates suggest the introduction of bobwhites to Cuba was human-mediated and concomitant with Spanish colonial shipping routes between Veracruz, Mexico and Havana, Cuba during this period. Our results identify endemic Cuban bobwhites as a genetically distinct population born of hybridization between divergent, introduced lineages.

RESUMO

This work adds a new eyeless species of the genus Micranops Cameron, 1913 (Staphylinidae, Paederinae, Scopaeina) to the endogean Coleoptera of the Bolivian fauna. The loss of eyes is usually associated with adaptations to subterranean habitats, although M. bolivianus Guzman & Zyla sp. nov. was collected from leaf litter. We also report new occurrences for the genus west of the Andes mountain range. Our work increases the number of known Neotropical Micranops species to seven and extends the known distribution range for the genus in South America.

RESUMO

Abstract This paper examines the development of the TECNO-ITINTEC museum, the first interactive science museum in Peru, which opened in 1979. The museum functioned under the Institute of Industrial Technology Research and Technical Standards (ITINTEC), a public institution established during the government of Velazco Alvarado. In 1975, Jorge Heraud became the president of ITINTEC's Board of Directors and proposed a science museum to inspire future generations of scientists. José Castro Mendívil joined as the exhibition's director and designer. Their motivation to open a museum coincided with the government's ideals for modernization and nationalization. This article analyzes various sources including newspapers, laws that regulated the institute, reports, and interviews with people involved in the museum to understand how science and politics intersected in TECNO-ITINTEC

RESUMO

Background: Defining Andean anurans through their altitudinal limits has been a common practice in species lists, studies of responses to climate change among others, especially in the northern Andes. At least three proposals to differentiate Andean anurans from lowland anurans through elevation and at least one to differentiate Andean anurans from high mountain anurans have been formulated. However, the most frequently used altitudinal limits are not based on theoretical or numerical support, but on observations or practical definitions. Additionally, these proposals have been applied equally to different portions of the Andes, ignoring the fact that even between slopes of the same mountain, environmental conditions (and therefore the distribution of species) may differ. The objective of this work was to evaluate the concordance between the altitudinal distribution of anurans in the Colombian Andes and four different altitudinal delimitation proposals. Methods: We constructed our study area in a manner that allowed us to include species from the Andean region (as traditionally defined) and adjacent lowlands, because if the boundaries criteria were applied they would separate the species of the latter by themselves. We divided the study area into eight entities according to the watershed and the course of the most important rivers. We conducted a bibliographic search for all anurans in the cordilleras and inter-Andean valleys of Colombia and complemented the search with information on anurans for the region available in the GBIF. After curing the species distribution points, we generated elevation bands of 200 m amplitude for both the study area and for each Andean entity. Subsequently, we performed a cluster analysis to evaluate the grouping of the elevation bands according to their species composition. Results: In none of the cases (neither for the entire study area nor for any of the entities) we found a correspondence of any of the traditionally used boundaries and the altitudinal distribution of Anurans in the Andean region of Colombia. Instead, on average, the altitudinal delimitation proposals arbitrarily spanned the altitudinal distribution of about one third of the species distributed in the study area. Conclusions: We suggest that, although, based on our results, some Andean entities can be divided according to the altitudinal composition of the species that occur in them, we did not find any results that support the idea of a generalizable altitudinal limit for the Colombian Andes. Thus, to avoid biases in studies that may later be used by decision makers, the selection of anuran species in studies in the Colombian Andes should be based on biogeographic, phylogenetic or natural history criteria and not on altitudinal limits as they have been used.

RESUMO

Refugia-based conservation offers long-term effectiveness and minimize uncertainty on strategies for climate change adaptation. We used distribution modelling to identify climate change refugia for 617 terrestrial mammals and to quantify the role of protected areas (PAs) in providing refugia across South America. To do so, we compared species potential distribution across different scenarios of climate change, highlighting those regions likely to retain suitable climatic conditions by year 2090, and explored the proportion of refugia inside PAs. Moist tropical forests in high-elevation areas with complex topography concentrated the highest local diversity of species refugia, although regionally important refugia centers occurred elsewhere. Andean-Amazon forests contained climate change refugia for more than half of the continental species' pool and for up to 87 species locally (17 × 17 km2 grid cell). The highlands of the southern Atlantic Forest also included megadiverse refugia for up to 76 species per cell. Almost half of the species that may find refugia in the Atlantic Forest will do so in a single region-the Serra do Mar and Serra do Espinhaço. Most of the refugia we identified, however, were not in PAs, which may contain <6% of the total area of climate change refugia, leaving 129-237 species with no refugia inside the territorial limits of PAs of any kind. Our results reveal a dismal scenario for the level of refugia protection in some of the most biodiverse regions of the world. Nonetheless, because refugia tend to be in high-elevation, topographically complex, and remote areas, with lower anthropogenic pressure, formally protecting them may require a comparatively modest investment.

Identificación de refugios para la biodiversidad de Sudamérica ante el cambio climático Resumen Las estrategias de conservación basadas en refugios ofrecen efectividad a largo plazo y minimizan la incertidumbre sobre las estrategias de adaptación al cambio climático. Utilizamos modelos de distribución para identificar los refugios del cambio climático de 617 especies de mamíferos terrestres y cuantificar el papel de las áreas protegidas en la provisión de refugios en Sudamérica. Para esto, comparamos la distribución potencial de las especies en diferentes escenarios de cambio climático, destacando las regiones que probablemente conservarán las condiciones climáticas adecuadas para el año 2090, y exploramos la proporción de refugios dentro de las áreas protegidas. Los bosques tropicales húmedos de zonas de gran altitud y topografía compleja concentraron la mayor diversidad local de refugios de especies, aunque también hubo centros de refugio de importancia regional en otras localidades. Los bosques amazónicos andinos albergaron los refugios ante el cambio climático de más de la mitad del conjunto de especies continentales y para hasta 87 especies a escala local (celda cuadriculada de 17 × 17 km2 ). Las tierras altas del sur del Bosque Atlántico también incluyeron refugios megadiversos para hasta 76 especies por celda. Casi la mitad de las especies que pueden refugiarse en el Bosque Atlántico lo harán en una sola región: la Serra do Mar y la Serra do Espinhaço. Sin embargo, la mayoría de los refugios que identificamos no estaban en áreas protegidas, las cuales pueden contener <6% del área total de refugios del cambio climático, dejando entre 129 y 237 especies sin refugio dentro de los límites territoriales de las áreas protegidas de cualquier tipo. Nuestros resultados revelan un panorama desolador para el nivel de protección de los refugios en algunas de las regiones con mayor biodiversidad del mundo. No obstante, dado que los refugios suelen encontrarse en zonas remotas de gran altitud con topografía compleja y menor presión antropogénica, protegerlos formalmente puede requerir una inversión comparativamente modesta.

RESUMO

Resumo A Escola de Farmácia de Ouro Preto, fundada em 1839, foi a primeira da América Latina desvinculada de uma escola de medicina. No final do século XIX, contou com um acervo de modelos anatômicos franceses dos renomados Deyrolle, Dr. Auzoux e Vasseur-Tramod, muitos fabricados em cera ou papel machê. O presente trabalho teve como objetivo resgatar, identificar, higienizar, restaurar e expor os modelos. De unidades acadêmicas da Universidade Federal de Ouro Preto, 17 modelos anatômicos foram resgatados e transferidos para o Museu da Pharmacia, onde receberam o devido tratamento. Os modelos em melhores condições foram expostos no museu formando parte da coleção de ensino do curso de farmácia de Ouro Preto.

Abstract The Ouro Preto School of Pharmacy was founded in 1839 and was the first pharmacy school in Latin America independent from a medical school. At the end of the nineteenth century, it had a collection of French anatomical models made by Deyrolle, Dr. Auzoux, and Vasseur-Tramod, many produced from wax or papier-mâché. This project involved recovering, identifying, cleaning, restoring, and exhibiting seventeen models found in various facilities from Universidade Federal de Ouro Preto. The models in good condition were exhibited in the Museum of Pharmacy (where this work was carried out) as part of the teaching collection for the Ouro Preto pharmacy course.

RESUMO

Abstract As of the nineteenth century, the number of world fairs and hygiene exhibitions grew significantly. This phenomenon was linked to the experience of modernity and the emergence of bacteriology, when different cities were sanitized with the aim of combating urban diseases and epidemics. For the purpose of sanitary education and hygiene propaganda, many objects and pictures were displayed in hygiene exhibitions and museums, such as the International Hygiene Exhibition of 1911 and the German Hygiene Museum, both in Dresden. The goal of this article is to analyze a chapter of the international history of health through images that portray the connections between the German Hygiene Museum and Latin American countries between 1911 and 1933.

RESUMO

During 1991, in Brazil, the presence of the exotic Bemisia tabaci B mitotype was reported in São Paulo state. However, the duration from the time of initial introduction to population upsurges is not known. To investigate whether the 1991 B mitotype outbreaks in Brazil originated in São Paulo or from migrating populations from neighboring introduction sites, country-wide field samples of B. tabaci archived from 1989-2005 collections were subjected to analysis of mitochondrial cytochrome oxidase I (mtCOI) and nuclear RNA-binding protein 15 (RP-15) sequences. The results of mtCOI sequence analysis identified all B. tabaci as the NAFME 8 haplotype of the B mitotype. Phylogenetic analyses of RP-15 sequences revealed that the B mitotype was likely a hybrid between a B type parent related to a haplotype Ethiopian endemism (NAFME 1-3), and an unidentified parent from the North Africa-Middle East (NAF-ME) region. Results provide the first evidence that this widely invasive B mitotype has evolved from a previously undocumented hybridization event. Samples from Rio de Janeiro (1989) and Ceará state (1990), respectively, are the earliest known B mitotype records in Brazil. A simulated migration for the 1989 introduction predicted a dispersal rate of 200-500 km/year, indicating that the population was unlikely to have reached Ceará by 1990. Results implicated two independent introductions of the B mitotype in Brazil in 1989 and 1990, that together were predicted to have contributed to the complete invasion of Brazil in only 30 generations.

RESUMO

This article reports on a historical investigation carried out on the conical object MIN000-3519 preserved in the mineralogy collections of the Muséum National d'Histoire Naturelle at Paris (France). The mineralogist René-Just Haüy (1743-1822) included this object, cut in a single pyrite (FeS2) crystal, in his working collection with the references 'Sulphured iron, mirror of the Incas, of Peru, M. de Jussieu'. All of the research lines followed lead the author to Joseph de Jussieu (1704-1779) and his shipments of botanical specimens and various other samples from South America. As a member of the Godin-La Condamine-Bouguer geodesic expedition on the equator (1735-1743), he returned to France only after 36 years (1771), ill, exhausted and dispossessed of the scientific product of his Andean collections. This pyrite mirror is important because, in addition to appearing to be the only archaeological object that can be linked to Joseph's peregrinations in America, it resembles other specimens found at sites of the Cañaris culture (500-1500 AD) in Ecuador. Preserved within the de Jussieu family, this object would presumably have been given to Haüy by Joseph's heirs, his nephews Antoine-Laurent (1748-1836) or Laurent-Pierre (1792-1866), with whom he had close ties.

RESUMO

Background: This database gathers 10,721 specimens, belonging to 2,578 species from the Chilean vascular flora (angiosperms, gymnosperms and pteridophytes) deposited in the Herbarium of the Pontificia Universidad Católica de Valparaíso (PUCV) in Chile. The PUCV botanical collection was started by the renowned botanist Otto Zöllner and represents a major natural historical legacy for central Chile, with decades of information represented through preserved specimens. This collection is currently deposited in the Curauma campus of the PUCV. This digitisation effort is part of the PUCV's endeavour to mobilise its biological collections and make them freely available through GBIF, encouraging national and international researchers to generate new knowledge, based on this invaluable heritage, which is a silent witness of the vast plant diversity that once existed in Chile and that is now vanishing due to anthropogenic drivers. New information: The database provides occurrence records from 10,721 specimens of vascular flora held in the PUCV Herbarium, representing 2,578 species, 914 genera and 177 families. Each record includes data on taxonomy, geographic distribution, elevation and collection information (e.g. date of collection, legitimavit and determinavit of specimens, general observations). The database serves as a repository containing records from past decades on the diversity and distribution of plant species, mainly from the Chilean Mediterranean biodiversity hotspot.

RESUMO

Although stable isotopes have been increasingly used in ornithology since 1980 in many places, Brazil has been slow in adopting this methodology, especially when it comes to terrestrial birds. The most common elements in bird ecology studies are carbon, nitrogen, hydrogen, and oxygen stable isotopes, which provide information on diet, trophic interactions, habitat use, migration, geographic patterns, and physiology. It is important that Brazilian ornithologists become aware of the potential of stable isotope analysis in ecological studies, and the shortcomings of this tool. The use of stable isotopes to study bird ecology has great potential in Brazil, since many ecological questions about Neotropical birds can be addressed by it (e.g., resource and habitat use, migratory routes, isotopic niches, anthropogenic impacts, individual specialization). Brazilian museums and other Natural History collections can provide samples to study long-term temporal dynamics in bird ecology. Additionally, the integration of avian tissue sample information into a database may increase the collaboration among researchers and promote sample reuse in a variety of studies. All biomes in Brazil have been under pressure from anthropogenic impacts (e.g., land-use change, habitat loss, fragmentation, intensive agriculture), affecting several taxa, including terrestrial birds. Considering the negative effects of human expansion over natural areas and that stable isotopes provide useful ecological information, ornithologists in Brazil should increase their use of this tool in the future.(AU)

RESUMO

Bees are a diverse group of insects that have tremendous importance as pollinators. In recent decades, there has been a global decline in bee populations because of land-use change, intensive agriculture, and climate change. Unfortunately, our knowledge of native bees' ecology is rather scarce, and such knowledge gaps are also a major threat to its conservation. In this sense, biological collections are a priceless natural history legacy and an information source for new research and decision making. Chile has a remarkable bee diversity, with 464 species currently known from Chile and a high incidence of endemism and a variety of habitats (including the Mediterranean biodiversity hotspot). The largest wild bee collection in Chile is held at the Pontificia Universidad Católica de Valparaíso (comprising a century of data). This collection has been recently included in GBIF. Here we present a database with 36,010 records, including information on sociality and ecology (including information on floral visitation range, the resource collected, and nesting substrates) for 160 out of the 167 bee species included (36% of the Chilean bee diversity, including 49 genera and five families). All records have the taxonomy resolved, and 83% of them have geographic coordinates, covering a latitudinal range between 18° S and 53° S from the continental and insular territories. This data set is released for noncommercial use only. Credits should be given to this paper (i.e., proper citation), and the products generated with this database should be shared under the same license terms (CC BY-NC-SA).

RESUMO

The type specimens of the New World Stigmoderini deposited in the Natural History Museum in London are catalogued and illustrated. Twenty-eight lectotypes are designated, one of which is a new lectotype, since the previous one is considered invalid under the article 74.2. (ICZN 1999). Holotype and in some cases, paratypes, are recognized for the following taxa: Conognatha nanula Hoscheck, 1934, Conognatha blairi Hoscheck, 1934, Hiperantha decorata var. insignata Hoscheck, 1928 and Hiperantha saundersi Théry, 1928. In addition, Lasionota oberthuri (Kerremans, 1897) rev. stat. is reinstated as a valid species, having been considered to be a junior synonym of Lasionota tetrazonus (Chevrolat, 1838) since 1997. The comparison of the reinstated species, with the recently described species Lasionota inca Moore Diéguez, 2019 showed that both are conspecific and hence L. inca syn. nov. is proposed as a junior synonym of L. oberthuri.

RESUMO

OBJECTIVES: We investigated the diversity of the pygmy marmoset, Cebuella pygmaea, by comparing genetic, morphological and pelage traits of animals from Peru and Ecuador. MATERIALS AND METHODS: We extracted DNA from museum specimen osteocrusts and from fecal samples collected from free-ranging individuals. We sequenced the mtDNA cytochrome b gene and the control region from samples collected at 13 different sites and used Bayesian inference and Maximum Likelihood to identify distinct clades. We took measurements of the crania of a subset of these specimens (n = 26) and ran a logistic regression to determine if any of the cranial measurements (n = 22) could predict a specimen's clade. In addition, we examined the pelage patterns of the museum specimens and photographs taken of free-ranging individuals and divided them into pelage types based on coloration of the underbelly. RESULTS: We identified two divergent clades, and two distinct groups with clear geographic boundaries within one of those clades. Two measurements of the zygomatic bone perfectly predicted a given individual's mtDNA clade. We found four distinct pelage patterns in our samples, but these patterns are variable within clades and among individuals within the same population. CONCLUSION: These analyses indicate that the two recognized subspecies of pygmy marmoset should be elevated to the species level (C. pygmaea and C. niveiventris) based on molecular and cranial differences but not on pelage patterns. We provide evidence on the geographic limits of the two clades and identify regions where additional sampling is required to better define the geographic distribution of the two clades.
